SPECIFICATION forming part of Letters Patent No. 773,442, dated October 25, 1904,

Application filed January 18, 1901. Serial No. 43,764. (No model.)

To (all whom it may concern:

Be it known that I, SAMUEL J .WEBB, a citizen of the United States, residing at Minden, in the parish of l/Vebster and State of Louisiana, have invented certain new and useful Improvements in Turbine-Engines, of which the following is a specification.

My invention relates to turbine-motors; and it consists in a stationary member composed of a conical casing with channeled partitions and a rotary member with channeled rings, as fully set forth hereinafter, and as illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section of a motor embodying my improvement; Fig. 2, a transverse section; Fig. 3, a sectional plan on the line 3 3, Fig. 2. Fig. 4: is a modification.

The casing of the engine is tapering or conical with a body 1, heads 2 8, and with separated annular partitions 4, each consisting of radiating blades each set at an angle to the.

axis of the casing, or each partition may be a ring slit to form angular blades. These partitions may be cast with or attached to the body 1. \Vithin the openings of the annular partitions fits, so as to turn freely, the body of the rotating member of the apparatus, which is carried by a shaft 6, turning in bearings of the heads 2 3, and which body carries a series of rings 7, arranged intermediatel y of the partitions 4, and each consisting of a series of radiating blades each set at an angle to the axis of the shaft, but in adirection nearly at right angles to the angle of the blades of the partitions A.

With the smaller end of the casing,beyond the terminal partition 4:, communicates an inlet-port receiving steam or other compressed motor fluid from any suitable source of supply, and at the opposite end of the casing is an exhaust-port.

The steam or other compressed motor fluid under high pressure passes through the inclined channels of the first partition 4 to the extent permitted by the aggregate area of said channels, and is thus directed in fine forcible streams almost at right angles against the faces of the blades of the next ring7, and thence passes through the channels of this ring and reacts against the blades of the next stationary partition, through the channels of which the steam is properly directed against the blades of the next ring, and so on, the rotary member being thus set in rapid rotation.

As the apparatus increases in diameter from the inlet to the outlet ends, the steam-motor fluid can correspondingly expand, and as the partitions and rings gradually increase in area there is a correspondingly larger area for the action of the fluid, which thus acts by a succession of expansions with decreasing pressures on increasing areas.

It is desirable to avoid friction between the moving and stationary members of the structure, and the rings of the moving member should therefore be maintained exactly in midposition between the partitions. This is done by means of a ring 9, inside the head 2, adjusted by set-screws 10 10, and by a set-screw 12, bearing on the end of the shaft 6. A pulley or gear 15 on the shaft is the means of communicating motion to any desired object.

Itwill be seen that the above-described apparatus is of extreme simplicity in construction, whereby a large percentage of the energy of an expansible fluid may be utilized at a comparatively small expense. The partitions A may consist of separated inclined blades projecting inward from rings fitting the inside of the casing, and each ring has a flange 20 or projection defining the distance of the partitions from each other.

Without limiting myself to the precise construction and arrangement of parts shown, I claim as my invention 1. The combination with the conical casing having an inlet-port at its smaller end and an outlet-port at its larger end, of a series of partitions each provided with radiating blades set at an angle to the longitudinal axis of the casing, the partitions being provided with v spacing-flanges, a shaft adjustably mounted in the casing, and a series of rings mounted on the shaft, said rings having separated blades arranged angularly on said shaft between said partitions, substantially as described.

2. The combination with the conical casing having an inlet-port'at its smaller end and an outlet-port at its larger end, of a series of partitions connected to the casing and provided with separated blades set at an angle to the other, substantially as described. longitudinal axis of the casing, a shaft niount- I 111 testimony whereof I have signed my name ed in the casing, adjusting devices at each end to this specification in the presence of two subol' the casii'ig for adjusting the shaft, and a scribing witnesses.

series of rings mounted on the shaft, said rings having separated blades arranged angularly on said shaft between said partitions, the channels between the blades in the partitions and those of the rings being at an angle to each SAMUEL J. \VEBB. \V itnesses:
